This tool is an improved version of the Graphic Training Aid 5-2-12 Coordinate Scale and Protractor used by United States and NATO military forces around the world. By using a slot on one side of the tool for access to the map, the tool can be more compact than the traditional GTA tool. The tool features several additional map scales, including 1:24,000, which is the most common topographic map scale found within the United States. The 1:100,000 scale now spans 5km grid lines, making it much more usable. Plus, he overall dimensions of the tool have been reduced so that it is the size of a music CD, easially fitting into a pocket or any slot where you could store a CD.
